The answer to that is always "Yes I do. A nobody with an inflated ego. Next question."
You can always tell a Harvard man. You just can’t tell him much.
Awhile back, at a large electronics store, a local TV personality - I knew him, a little, he was rude and full-of-himself - pushed to the front of the (long) line. Clerk questioned him and he gave her the "Don't you know who I am?" line.
It was dead quiet. Clerk looked him and down for about 20 seconds, then slowly shook her head and said "No.", and turned to help the person who had been waiting in line.
Perfect squelch to this jerk's ego.
